New Features Found in Einstein's Brain
In 1999, an anatomical study of Einstein's brain was made. Interestingly, reports Science Now, his brain was smaller than average:
"One parameter that did not explain Einstein's mental prowess, however, was the size of his brain: At 1230 grams, it fell at the low end of average for modern humans."
This meant that it was necessary to study the other intricacies of his brain. If Einstein's overall brain were at the smaller end, perhaps there were other things to find. The 1999 study by a team in Canada found that Einstein's parietal lobes were 15% wider than average. Science Now points out that these lobes are usually connected to spatial and visual cognition, as well as mathematics.
A new study has found even more differences in Einstein's brain. Dean Falk works at Florida State University and has studied the photographs of Einstein's brain in detail. In addition to the parietal lobes, Falk claims to have discovered a pattern of ridges and grooves in those wider lobes that is rare. This rare pattern is thought to have contributed to Einstein's visual thinking when it came to physics.
"[ I ]n other studies, similar "knobs" have been associated with musical ability. (Einstein had played the violin avidly since childhood.)"
The idea is that what made Einstein a genius has more to do with the structure of his brain, than its size. However, it is important to keep in mind that Einstein's brain in its totality can only be studied via photograph and compared to other photographs. And, of course, the brain is a complex and still-mysterious organ. But it may be that we can glean some additional insight from studying the structure of Einstein's brain.
